Abstract

A method of manufacturing a conveyor belt having an elongate body made of uncured rubber and/or synthetic rubber. A polymeric parting material is placed adjacent to the upper and lower surfaces of the body, and heated platens are applied to the upper and lower surfaces of the body (i.e. belt material) to soften the adjacent upper and lower layer portions of the belt. This causes the softened belt material to flow into interstitial openings in the parting material. The resulting belt has the parting material squeezed into a thinner layer and embedded in the adjacent surface portions of the body of the belt. This provides a substantially uniform and reflectively soft texture surface.
